  • the display both while driving as well as when the bike is stationary. At standstill are at least profile data of the route, namely slope or slope. As soon as the bike starts moving will be transferred by processing the profile data and the current trip data, information supporting the driver generated that relieve him.
  • the best possible gear ratio of the gearbox is displayed as well as in steps of the best possible translation level neighboring translation levels. The latter measure leaves the driver has several options of appropriate gear ratios. The driver can use these within these gear ratios Select higher or lower pedaling torque to be applied. Using one of the translation levels will be rough Switching errors avoided.
  • the longitudinal inclination sensor and the bank inclination sensor of the inclination measuring system are advantageously designed as micromechanical acceleration sensors and the control electronics have means for determining that portion of the measured acceleration which is initiated by the driver when driving uphill or downhill and which acts in the direction or counter to the acceleration due to falling. Because micromechanical acceleration sensors are provided for the inclination measurement, a precise and linear inclination angle measurement is possible with a minimal size of the inclination measuring system.
  • the acceleration sensors each measure a total acceleration, which is composed of the respectively effective component of the gravitational acceleration of 9.81 m / s 2 , which is constant in the earth's gravitational field, and the acceleration component initiated by the driver, which acts in the direction of or against the gravitational acceleration.
  • the towards or against the active component of the Fall acceleration effect and initiated by the driver the measured longitudinal acceleration is simply derived from the Quotient of a change in speed and the time interval calculated in which the speed change took place Has.
  • the time interval can, for example, from the measured wheel speed be calculated.
  • the control electronics have the ability to display the longitudinal direction of the route Means for forming the difference between the measured Longitudinal acceleration and that initiated by the driver Share of longitudinal acceleration.
  • the so determined Acceleration difference is used to calculate the Track slope used.

  • the two aligned sub-circle sectors form one Luminescent pointer, which can have three different lengths.
  • the Luminescent length 'zero' indicates that there are no longitudinal and none Bank is present. If the luminous pointer length of the Corresponds to the length of the pitch circle sector of the inner circle, there is a low overall tendency. Corresponds to the length of the luminous hands the sum of the length of the inner circle sector Circle plus the length of the outer part circle sector, so there is a higher overall tendency.
